Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
scale studies » case studies, scale study
da filosofia » la filosofia, di filosofia, a filosofia
vast scale » bast scale, coast scale, best scale
studies da » studies dna, studies das, studies dan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: vast scale studies da filosofia ((y literatura) OR (la literatura))*.
